Answer 1

`\Huge \boxed{8x^2 +5y+1}`

`\rule[225]{225}{2}`

Explanation:

`1+x^2-3+2y+7x^2+3+3y`

Grouping like terms.

`7x^2 +x^2+2y +3y +3+1 -3`

`(7x^2 +x^2)+(2y +3y) +(3+1 -3)`

Answer 2

8x^2 + 5y + 1

Explanation:

1 + x^2 - 3 + 2y + 7x^2 + 3 + 3y

group like terms

= x^2 + 7x^2 + 2y + 3y + 1 - 3 + 3

add similar items

= 8x^2 + 2y + 3y + 1 - 3 + 3

add similar items

= 8x^2 + 5y + 1 - 3 + 3

= 8x^2 + 5y + 1
